Deep Learning Based Unsupervised and Semi-supervised Classification for Keratoconus [PDF]
arXiv, 2020 The transparent cornea is the window of the eye, facilitating the entry of light rays and controlling focusing the movement of the light within the eye. The cornea is critical, contributing to 75% of the refractive power of the eye. Keratoconus is a progressive and multifactorial corneal degenerative disease affecting 1 in 2000 individuals worldwide ...

In vivo Terahertz Sensing of Skin Cancer Patients
Advanced Photonics Research, EarlyView.This study presents the first in vivo measurements of skin cancer patients in a hospital setting using a handheld THz probe. Furthermore, a new analysis approach is developed to generate a patient‐normalized THz response function, which enables clear contrast to be seen between cancer and healthy skin of the same patient.The first in vivo study of skin

Spatially-resolved Brillouin spectroscopy reveals biomechanical changes in early ectatic corneal disease and post-crosslinking in vivo [PDF]
arXiv, 2018 Mounting evidence connects the biomechanical properties of tissues to the development of eye diseases such as keratoconus, a common disease in which the cornea thins and bulges into a conical shape. However, measuring biomechanical changes in vivo with sufficient sensitivity for disease detection has proved challenging.

Measuring the visual angle of polarization-related entoptic phenomena using structured light [PDF]
arXiv, 2023 The ability to perceive polarization-related entoptic phenomena arises from the dichroism of macular pigments held in Henle's fiber layer of the retina and can be inhibited by retinal diseases such as age-related macular degeneration, which alter the structure of the macula.
